IMPROVEMENT lN NAIL-PLATE FEEDERS.

Specification forming part of Letters Patent No. 180,928, dated August8, 1876; application filed April 18,1876.

To all whom it may concern:

Be it known that I, WM. H. RITTENHOUSE, of Norristown, in the county ofMontgomery and State of Pennsylvania, have invented a new and ImprovedTack -Machine Feeder, of

which the following is a specification:

The invention will first be described in connection withdrawing, andthen pointed out in the claims.

Figure l is a sectional elevation of my improved machine, taken on theline a: w of Fig. 2. Fig. 2 is a plan view. Fig. 3 is a section on liney y. Fig.4 is a section on linez 2. Fig. 5 is a section on line to w,and Fig. 6 is a section on line 0 n.

Similar: letters of reference indicate corresponding parts.

A is the barrel, which turns in the bearing B, and on the bed-plate C,under the springbearing D, being turned by a ratchet pulleyring, E, beltF, and oscillating shaft G, the ratchet being contrived to turn it-ahalf-revolution to each operation. The shaft is geared by pinion H andwheel I with the rocking crank-shaft J, the crank of which is coupled bylatch M with the stud of pin N, which couples the connecting-rod O ofthe main crank-shaft to the lever P, which gives motion to the header.The barrel has a slot, Q, extending along its whole length between thebearings, through which slot a pin, R, couples the feed ring S with thenipper head T, so that the nipper can be fed by a weighted cord, U, atthe same time that the barrel revolves.

The ring S works between two collars, V,

up the ledge Y when the feeder is set back, detaching it automatically.

a represents the two spring nose pieces to the barrel, which I employinstead of the one rigid one heretofore used, in order that when thebarrel is turning over on one of them its weight and the pressure of thebearings D will spring it, and so nip the plate that it will not feedwhile turning.

The blank from which the nail is cut obliquely across has one edgelonger than the other, necessarily. As the reciprocal feed turns thelong and the short edge up alternately, in ordinary nail-plate feeders,high speed is not possible, because the moving knife lifts the platefrom the bed-knife when, in turning, the long edge is up. On the otherhand, when the short edge is up, and the nose-piece made to spring andbind the plate, the moving knife will clear it every time, and there isno limit to the speed, so far as the feed is concerned. I

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is

1. The pin R, spring W, ring S, and collar V, combined with thenipper-head T, revolving barrel A, and weighted cord U, substantially asspecified.

2. The pin R, having incline X, in combination with spring W and ledgeY, substantially as specified.

3. The ratchetring E, belt F, oscillating shaft G, Wheels H I, andcrank-shaftJ, coupled to the header-lever, and combined with therevolving barrel, substantially as specified.
